Rate (mL/hr) = Total Volume (mL) / Time (Hours)

Determines the setting for an IV infusion pump based on total volume and desired duration.

1000 mL over 8 hours -> 1000 / 8 = 125 mL/hr.

Most electronic infusion pumps are programmed in mL per hour to ensure consistent and precise fluid delivery over a long duration.

Infusion rate (mL/hr) is for pumps, while drip rate (gtt/min) is for manual IV gravity sets where you count the drops.

Divide the minutes by 60 to get hours. For example, 30 minutes is 0.5 hours.
